DementiaCraft

by lanse

DementiaCraft is a server-side Fabric mod for Minecraft 1.20.1 that reshapes the terrain a player sees around them, turning the world into a catacomb-like space.

What it does

Players who look in a given direction find the world rebuilt around that view. Terrain is regenerated from the direction a player is facing, using a custom chunk loader that reshapes the area around the player and corrupts the rest of the world. The author describes the effect as a remake of the Catacombs Solaris and Lobotomy modes, where only what is looked at is replaced and everything else stays unchanged.

The mod is an extension of FractalWorld that grew into a separate project. The author describes it as a precursor to a larger remake of Oasis AI, and the screen is built from terrain that the mod generates around the player. Commands start with a dedicated prefix, and a low-quality showcase video is linked from the author text. The project is open source under the MIT License and its source code is public.

DementiaCraft is published only for Fabric, for 1.20.1, as a beta release. The latest file is 2.0.0, dated 2025-02-16. The mod runs on the server alone, so players join without installing it. Its first publication date is 2025-01-18.

Key features

  1. View-based terrain

    Terrain around the player is rebuilt from the direction they are facing, so the effect changes as the view turns.

  2. Custom chunk loader

    A custom chunk loader handles the reshaping, applying the changes in a dedicated corrupting process over the world.

  3. Catacombs-style mode

    The author describes a single mode based on the Catacombs Solaris and Lobotomy effects, replacing only the looked-at area.

  4. Command prefix

    Commands start with a dedicated prefix, and the author text lists them in the project notes.
